loall whom it may concern."

Be it known that I, SAMUEL E. Hummer, Heertwell, in the county of Kearney and State of Nebraska, have invented. certain new and useful Improvements in Incubavtors, of which the following is e specification.- This invention relates to. incubators, and more particularly totreys therefor. 1

tray so constrected that all of the eggs rnoy turned simultaneously by a single operat on Another ob1eet-1s to this character with rotetebly mounted, re movable egg supporting rollers and ior holding" the rollers egeinst vertical v and. claimed, it changes in the precree.,,embo lunent or the view, which will appear movement, While being turn'ecl.

Another object is to provide a, simple and easily operated means "for eunultene ously rotating the rollers 2 With the foregoing and other objects in as the description proceeds, the invention IESldBS'iIl the combierrengement of parts and in the details of construction hereinafter cleecriberl laying nn lerstoocl that invention herein dhclosed may be made with n the scope of whet 1S claimed wltliout ilepa-rting from the spirit of the invention In the accompanying drewinge:

I Figure 1 represents a plan view of an inculoator trey constructed in accordance with this invention. y r

Fig. 2 is an end elevation. thereof, Fig.

.11 the embodiment illustrated, a trey 1 is shown which, may be ofany suitable or desired size or shape according to the incubetor in connection with liich it is to be used,l it being lrere ehowrirectengular. v This through trey 1s composed of encl members 2 con faceted by'ieide members, 8, said members being constructed of Wooden strips or here about one and a hall' inches wide more or less, anti :1 fonmninous bottom 4: is securedto the lower edges of seitl'rnembere. This bottom is preferably constructed from screen vvi-le, although it may be composed oifanyotlier suitable foraniinous material which the heat myyee for cirroletion eroiind the eggs. bersfl are provided with a plurality of lonperform the of: the invention is; I

iieted, eml any lie employed,

provide a trey of screws 3 ie a transverse section taken on of the tray ale I The enrl rne'ln giturlinelly spaced. notches 5 here shown in the form of slots, those in one end member being arranged. diametrically opposite those in the other end member, and which are to function of bearings for journals 7, formed at theencle of rollers 6.

These rcllerefiyvliieh are preferably constructeri of Wood or similar material are esigned to support vthe desired number thereof may fourteen being here shown. The journals 7 of these rollers 6 are here shown in the iorzn cf screws, inserteclin the ends of the rollers rengecl on the out-er feces of the end morn-- bore 2, the-shanks or body portions of the being inserted in the "bearings formed loy-the slots 5 as is shown clearly inlf'igel and between the ends or the rollers, and the atljacent end walls to permit the free turning or" said rollers.

' -Tl1e end members 2 are each provided on their inner faces above the seats in which the journals 7 are disposed with. a longitudinally extending groove designed.

eggs to be incuwith {heads thereof er-' 2, suilicient space being left driving: smell staples in the end members? "withv their le v saennin itlie rooves w b is oi sown clearly in ilfig. 3. Each wire rod 9 preferably proviclecl at one engl with eieterellyeextendmg finger L1 to facilitate its this Wire must be removed. before the rollere can be taken out, and which ie necessary once aronno ther intermediate rollers asis shown clearly nf-1g 1. The cord pesses below the rollergv ancl is WOllIld' upwardly Thiscorcl is arounol them from riglit'to left. also wrapped around the rollers am is posi-v tioneci at an angle from one sirle to the other is shown clearly in Fig. 1 to revent liintling thereof when the rollers are icing tnrnecl.

insertion and removal, itbeingobvions that ceive crank handles 13 which are designed I for turning the rollers. By positioning one of these crank handles at each side 01 the tray, the rollers may be turned and the eggs su ported thereby rolled either way froin eit ier end of the tray, thereby facilitating the turning operation.

From the above description, it will be understood, that when it is desired to turn the eggs all that is necessary is to grasp one of the crank handles 13, and turn it, which turns the roller with which it is connected, and through the flexible element 12 simub taneously turns all of the rollers and thereby rolls the eggs from one side to the other which is necessary to insure a reliable hatch. It will also be seen, that by posi tioning the Wire rods 9 above the roller journals, the end rollers will be prevented from rising When they are turned and also the intermediate rollers will be held in their proper position thereby,

On the eighteenth day, when the eggs are turned for the last time, the wire rods 9 are withdrawn from the tray by moving them longitudinally out of the guide loops 10, and the rollers may then. be taken out, and the eggs dropped down on to the screen bottom 4 where they will remain until the chicks come out.

v It will thus be seen that this tray, while simple and cheap in construction is very efiicientlin operation and that by a single turning of a crank handle all of the eggs co d in the tray may be simultaneously aerato turned, thereby greatly lessening the labor usually incidentto such turning. From the foregoing description, taken in connection with the accompanying draw-- ing, the advantages of the construction and of "the method. of operation will readily be apparent to those skilled in the art to which the invention appertains and while I have described. the principle of operation of the invention, together with the device which 1 now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope oi. the claimed invention.

1 claim:

An incubator tray including opposed upright members having a plurality of longitudinally spaced notches in their upper edges and a groove arranged loosely on the inner face of each of said members above the bottoms of said notches, rollers having their ends journaled in said notches, a wire rod positioned in each of said grooves, inc-an for retaining each rod in said grooves, and permitting it to slide longitudinally, the two end rollers having one of their ournals made angular to receive a crank handle, and a flexible element wound. around said roll.- ers and inclined from one end roller to the other.

In testimony whereof 1i affix my signature in presence of two witnesses.

SAMUEL E. HARPHAM.
